^aA registered day is defined as a day that was reviewed and approved by participant as valid data regarding their travel behavior that day (ie, number of minutes spent walking, cycling).

^bThe maximum total number of days was 84 days since results are reported for 3 months or 12 weeks (ie, 0-3 months [intervention period] or 3-6 months [3-6 months after the intervention]).

^cThese categories correspond to <1 week, 1-4 weeks, 4-8 weeks and 8-12 weeks.
